phroditic plants), Thalictrum, Potentilla maculata, Draba crassi- 

 folia, Oxyria, Erigeron uniflorus, Salix arctica, Carex rigida 

 {in great numbers). A great many winter-nests and other 

 traces of lemmings were found. 



Abt. 250m above sea level: Large Cassiope hypnoides and 

 C. tetragona in full flower. The air smelt sweet from the white 

 corollas of Cassiope tetragona^ which were industriously visited 

 by humble-bees. 



Abt. 330 m above sea level : On the solid basalt Usnea 

 melaxantha was very common. Here a rich insect-life had 

 developped: Argynnis, wasps djaå Syrphidae, besides numerous 

 dancing gnatworms. 



Large, dense cushions of Ardostaphylos alpina covered the 

 field, which here consisted of débris of basalt; this species was 

 not seen farther down the mountain. 



At this height were noted besides : Potentilla nivea, Saxi- 

 fraga tricuspidata and S. oppositifolia, Dryas octopetala, Carex 

 nardina, Pedicularis hirsuta, Cerastium alpinum, Polygonum vivi- 

 parum, Ranunculus arcticus with its var. Wilanderi, Arnica alpina. 



This latter evidently turned its big yellow flowers after the 

 sun; all its flowers stood clearly oriented after the direction 

 of the sun. 



Cape Dalton (Chr. Kruuse). 



The lowland surrounding the lagoon, as well as the littoral 

 region, was totally devoid of vegetation. The north side of 

 the valley is formed by a steep basaltwall, which out in the 

 bay ducks its foot directly in the sea, whereas landwards it is 

 covered by débris consisting of coarse, sharp-edged blocks. 

 In many places the snowcoating is still thick, and the débris 

 is devoid of vegetation except in the few places where a little 

 basalt-rock sticks out and thus forces the water to the surface. 

 Here were noted tufts of Cassiope tetragona, some crumpled 

 individuals of Salix arctica, Polygonum, an isolated Ranunculus
